MACHINE FOR CORRUGATING AND EDGING SHEET METAL.

SPECIFICATION forming part; of Letters Patent No. 382,277, dated May l,1888.

Application tiled January 20, 1888. Serial No. 261.888. (No model.)

To aZZ whom, it may concern.-

Be'it known that I, EMIL R. STASCH, a citizen of the United States,residing at Corning, in Steuben county, and State of New York,

have invented new and useful Improvements in Machines for Oorrugatingand Edging Sheet Metab of which the following` is a specification.

Sheet-metal roofing, when laid and seamed, has a fullness or surfaceloosencss upon the roof-boards, which is the cause of more or lessnoise, like a cracking sound produced by persons walking over it, due tothe effects of expansion and contraction, and it is, moreover, liable torattle from wind getting under it.

My improvement is designed to avoid these objections, to stiffen andbrace the sheet-roof ing, and to give it a firm flat seating upon theboards, so that the seamed sheets will have a tightness that willprevent all cracking and rattling noise when properly secured. For thispurpose I have produced a machine by which the sheets which are to beseamed together for ythe roof are formed with`corrugations within thebody of the sheet, as will be hereinafter described, so that when thesheets of a longitudinal strip are soldered together, edged, and joinedby the seaming operation they will be stiffened and braced in linescrosswise to the lines of the seams, and thus cause the roofing to lieflat and rm upon the boards, the corrugations serving to take up thefullness not only of each sheet, but of the connected sheets throughoutthe roof.

The sheets can be corrugated separately for what is known as flatseaming;7 but for vertical seaming they must be soldered together beforebeing corrugated, because in roofing a house the sheets are solderedtogether at the shop in lengths and taken in rolls to the place for usewhen the work is to be done with ver tical seaming. In such oase theoperations of corrugating and of edging for the seam are done in thesame machine by passing the soldered length of sheets through it in oneoperation.

My invention therefore embraces a machine adapted for corrugating singleroofing-sheets, and for corrugating and edging at one operation thesoldered length of sheet for roofing.

5o Iprefer for this purpose to construct the machine with edging devicesadapted for adjustment into or out of use, as may be desired, aclcording to the'work to be done without interfering with the operation ofcorrugation, so that one machine will be suited for both kinds of work.In the accompanying drawings I have illustrated such a machine, which,when constructed for use, will be portable so as to be taken by thetinner to his work.

Referring to the drawings, Figure l rep- 6C resents a side elevation of'my corrugatingmachine. Fig. 2 is a vertical longitudinal section of thesame, the soldered length of sheet being shown in dotted lines as it isfed from the reel to the corrugatingrolls. Fig. 3 65 '1 is acrosssection ofthe n1achine,taken through the axes of thecorrugating-rolls. Fig. 4 is a rear view ofthe machine. Fig. 5 is a topView of the machine. Fig. 6 represents a portion of two sheets solderedtogether and corrugated 5 7g and Fig. 7 is a crosssection of themachine, taken in the line 2 2 of Fig. 5. Fig. 5LL shows a detail of thedetachable head of the reel.

The machine will weigh about thirty-five pounds, the operating partsbeing mounted in a suitable frame so as to permit the sheet to be fed atone end to the corrugating-rolls, and to be edged, if desired, as itleaves them at the other end of the machine.

Withinsuitable bearings of the side frames, 8O A,and at about themiddleof their length,are mounted, crosswise, rolls B and C, onevertitically above the other, and preferably placed so that theirmeeting lsurfaces will be about on a level with thetop of the frame.These rolls are provided with registering surface projections andrecesses adapted to corrugate a sheet when passed between them. I preferto form the surface projections a upon the lower roll, and to disposethem equidistant, as shown in Fig. 2.

The projections shown are of a very wide V shape, having its armstapering 'to points toward the ends of the cylinder, as seen in Figs. 4and 5. The rib-arms, however, do not 95 extend to the end of thecylinder, but are of sufficient length only to forni the corrugationswithin the body of the sheet, as seen in Fig. 6, so that suchcorrugations will not extend to the edges of the sheet. The greatestsurface roo projection of these ribs is at the angle of the V, and fromthis point such projection gradually decreases to the ends of the arms,so1 that the corrugations in the sheet will gradually terminate at thesurface thereof. The upper roll has recesses b,.corresponding in depthand form to the surface projections of the lower roll and registeringwith them. The number of these surface registeringroll projections andrecesses may be two or more, (three being shown,) and they will producea corresponding number of corrugations in the sheet, as shown.v Theupper corrugated roll is mounted in sliding boxes c, held down by thepressure of springs d and screws e, whereby the upper roller is free toyield, for a purpose which'I will presently describe.

The upper roll is formed near its ends with circumferential ribsf, andthe lower roll has corresponding grooves g, which together serve togroove or indent the sheet while being corrugated sufficiently to startthe line at which the sheet is edged or bent for the seam outside of thecorrugations.

Provision is made for removably mounting a reel, D, upon the front endof the machine, to receive a roll of tin, so that it may be fedtherefrom to the corrugating-rolls, as shown in Fig. 2. To permit theroll to be slipped upon the reel, one of its heads, D, is maderemovable, as shown in Fig. 5, so as to be taken olif .when the roll oftin is to be slipped over and upon the reel-rods, the reel for thispurpose being removed from its bearings, which may be of anyconstruction'to permit of such. removal. Referring to this removablehead D of the reel, (shown in detail, Fig. 5,) such removal may be madeby making the head D like a plate-ring, and securing it by screws 8 tothe outer 'face of a head, D2, fixed to and connecting the ends of thereel-arm, so that by taking the screws 8 out the head is free to beremoved. The roll of tin can then be slipped upon the reel-arms, overthe head D2, and the ring-head again secured in place. The reelheadssimply serve to hold the sheet-roll, so that it will unwind true to thecorrugatingrolls.

The rolls are geared together by equal gears E E, and the top roll-shafthas a fly-wheel, F, provided with a. crank by which to operate therolls, the speed of which being equal seize and feed the sheet betweenthem in corrugating it. In corrugating the soldered length of sheetsprovision is made in the machine for edging the sheets at the sametime,so that they may be seamed together in laying the roof. I prefer,however, to make such provision capableofnon-use,so that the machine maybe used for corrugating the sheets only-as, for instance, when they areto be used for dat seams. This edging of the sheet is effected graduallyby rolls arranged in two or more pairs on each side of the machine inpositions to receive the edges of the sheet and bend and turn them up asthe sheet leaves the corrugating-rolls. For this purpose one set ofrolls, G H H2, is formed to commence the bending of the sheet at itsedges as it leaves the corrugating rolls, while the other set of rollsat the end of the machine is formed to complete the edging of thesheet.Of the first set of rolls the upper roll, G, of each pair is formed oftwo truncate cones joined at their bases, while the lower roll of eachpair has a cylindrical part, H, joininga truncate part, H2, at itstruncate apex, so that this latter part stands inward. Each pair oftheserolls is mounted on bearing-arms h h of brackets t', suitablysupported upon the side frames, and the relation of these rolls is suchthat the edges of the sheet will pass between them as it emerges fromthe corugatingrolls.

`The rolls for this purpose, like the corrugating-rolls, are supportedin separated relation, so that thejoining of the cones of the rolls Gwill stand in line with the starting-bend fin the sheet, (see Fig. 6,)and in line with the joining of the lower roll parts, H H2, in suchmanner as to bring the surface of the innerv cone part ofthe upper rolland the surface of the inner cone part of the lower roll in ahorizontalplane coincident with the meeting surfaces ot the corrugating rollscorresponding with the unbent part of the sheet. The outer cone part ofthe upper roll and the outer cylindrical part of the lower roll willstand at their meeting surfaces atan upward angle sufficient to startthe edging of the sheet and permit such edgebent part to enter and beforced between rolls which bring such bend to a right angle, as shown inFig. 4, in completing the edging of the sheet.

The sheet in passing from the rolls will strike between the rolls whichstart the edg ing bend, so as to bring the grooves j", made in the sheetby the ribs and grooves of the corrugating rolls, at the angles betweenthe planes of the rolls, so that the edges or iiangcs outlined by thecorrugatiug rolls will be bent up ward,as stated. v

'A roller, I, is journalcd in the side frames in position to receive andsupport the sheet as it leaves the rolls G H and guide it to theedge-itinishing rolls, which I will now describe. The rolls J and K aremounted in pairs upon vertical bearings ofsuitable brackets, L, securedto the side frames, the rolls being separated so as to permit thebent-edge part of the sheet to pass between them. The outer rolls ofthese pairs have anges k ontheir lower ends, which serve to support thesheet as it passes between them and while it is being edged or turned upvertically at the edge, so that the sheet will pass out of the machinecorrugated and edged, ready for seaming.

The several pairs of edgingrolls may be mounted so that they may beturned over with their brackets out of the way, as shown IOO IIO

IIS

by dotted lines lin Figs. 4 and 7, and thereby adapt the machine forcorrugating single sheets for fiat seaming. prefer to so hinge thebrackets to the frame that they can be turned upward andvoutward, andwhen so used the reel is removed and the single sheet can then becorrugated and grooved alongthe edges. In this way the For this purposeI` machine is adapted for corrugating sheets that are soldered togetherfor vertical seams, or for corrugating single sheets for flat seams.

Y In corrngating the soldered sheets the upper roller will yield toallow the soldered joint l, Fig. 6, to pass between the rolls. In thisfigure I have shown the sheets soldered together and the edging indotted lines; but it will be understood that when the single sheets arecorrugated they are not also edged. But of whatever form,these middleregistering projections and recesses, they should act to take up thefullness ofthe sheet in every direction of the sheet. Thereforeprojections and re cesses running in the line of the axes of the rollsonly would be insufficient for the purpose of myinvention, because suchcorrugatious in the sheet would only take up the fullness in onedirection-thatis, in the length of the connected sheets, but not atright angles to such length, and the sheets would for this reason whenlaid be full and comparatively loose along their senmeonnected edges.This is the difficulty my invention overcomes, by causing thecorrugatious in the sheet to stand obliquely to the lines of the seams,so as to draw the fullness of the sheet into the corrugatious from thedirection of the edges which are to be seamed and from thedirection ofthe edges which are connected in the strip-that is, from the fourdirections. There is another advantage inthe preferred form of theseregistering projections and recesses, and that is, the constructionwhich gives the greatest depth to the corrugatious along the middle ofthe sheet, and from this point the oblique arms of the projectionsgradually diminish and terminate in pointsat the surface, and therebyprevent the puckering or ridging of the metal along the seaming line ateach edge. For this purpose the projections are made widest and of thegreatest surface projection at the mid dle of the length of the roll,and from this point the arms taper or decrease both in width aud surfaceprojection, and terminate in points coincident with the surface of theroll, so that in effect the fullness of the sheet is concen- -trated atthe middle or central line of the sheetnietal strip throughout its wholelength.

'The projections and recesses occupy a comparatively small portion ofthe surface of the rolls, leaving the balance unbroken to make contactwith those portions of the sheet which are not acted upon by theregistering parts of the rolls.

I am aware that it has been proposed to cor rugate sheet metal so as toleave unbroken margins at the edges, which stand at right angles to theline of such corrugatious, and in which both surfaces of the sheet arecorrugated, so as to form projections and recesses alternating, makingeach surface with gutters or grooves below the latter separated byprojections above the surface.

I am also aware that it has been proposed to form such corrugatious bothas to the grooves` and as to the ridges in longitudinal serpentine orwavy lines of equal width and projection throughout their length, andtherefore terminating above the unbroken surfaceof the sheet on bothsides thereof. It would be impractieable, however, to use sheettincorrugated in this way for roofing, for the reason that itssurface-gutters, standing at right angles to the seams, would collectand hold water and dirt over the entire surface of the roof between theseams, whereas by my improvement the corrugatious or ridges are formedin the upper side only of the sheet with intervening unbroken surface.and with the corrugatious so formed as to shed the water and prevent thecollection of dirt, and for this purpose the hollow sides of thecorrugatious stand downward, so as to permit the water to run off aroundthe upper inclined sides of the corrugations. This is an advantage notpossible in parallel wavy corrugatious forming alternate surface ridgesand gutters, It is obvious, there fore, that rolls having their surfacesbroken by alternate projections and recesses above and below thesurface, and having such corrugations, formed in longitudinal parallelserpentine or wavy lines, are not adapted to carry out my invention. j

The machine will save time and labor in seamin g the roof, and may bereadily operated by hand. The edging may be done on a separate machine;but when the edging-rolls are used in the same machine with thecorrugating-rolls, they are rmly supported by their brackets and uponprojectionsnnof the frame. When the edgingrolls are not adapted to beturned over out of the way, they muy be supported in any suitable way.
